b = 0.1a
c = 0.2b
We have to find:
x=0.3c
Solve first two equations by putting values
c=0.2b
c=0.2(0.1a)
c=0.02a
Now,
x=0.3c
x=0.3(0.02a)
x=0.006a = 0.6% of a
Option D
c = 0.2b
We have to find:
x=0.3c
Solve first two equations by putting values
c=0.2b
c=0.2(0.1a)
c=0.02a
Now,
x=0.3c
x=0.3(0.02a)
x=0.006a = 0.6% of a
Option D
